We employed microelectrode recording techniques to study the sensitivity of individual neurons in the striate cortex of anesthetized and paralyzed monkeys to relative interocular image disparities and to determine the effects of basic stimulus parameters on these cortical binocular interactions. The visual stimuli were drifting sine wave gratings. After the optimal stimulus orientation, spatial...

Despite an absence of causal evidence showing that limited access to healthy foods is to blame for unhealthful consumption, policies aimed at improving poor diets by improving access are ubiquitous. In this paper, we use novel data describing both the healthfulness of household food purchases and the retail landscapes facing consumers to measure the role that access plays in explaining why some...

This paper is a conceptual analysis of the effects of racial residential segregation, which is a major contributor to racial and ethnic health disparities. Metropolitan segregation has had adverse health consequences for economically disadvantaged and minority populations because they are exposed to higher levels of environmental pollutants and have limited opportunities to gain a quality educa...

  Background :There is substantial lack of knowledge about the role of socioeconomic status (SES) indicators on life expectancy (LE) within-cities, especially within mega-cities. We aimed to investigate the disparities of LE within city districts of Tehran, Iran, and specify how SES inequalities play role on LE.   Methods : The death and population data for 2010 by different age, gender, and re...

Cities are centres of social, cultural, economic and material diversity, where people in the most diverse living situations meet densely populated areas social inequalities or disparities can manifest intensify through spatial concentration population groups. Due to increase inner-city disparities, numerous German-speaking (large) cities have started establish small-scale area reports order be ...

The striking growth of online communities in recent years has sparked significant interest in understanding and quantifying benefits of participation. While research has begun to document the economic outcomes associated with online communities, quantifying the social value created in these collectives has been largely overlooked. This study proposes that online health communities create social...

BACKGROUND Cancer health disparities by race, ethnicity, socioeconomic status, and geography are a top public health priority. Breast and colorectal cancer, in particular, have been shown to exhibit significant disparities and contribute a large proportion of morbidity and mortality from cancer. In addition, breast and colorectal cancer offer targets for prevention and control, including nutrit...
